ALPHA Hawker Typhoon Procedures

Pilot's Notes:

The Typhoon was a troublesome aircraft from the beginning, and not for novices.  The powerful, sophisticated Napier Sabre engine, coupled the enormous 14-foot propeller, created tremendous torque on takeoff and required a smooth, steady hand at all times.  This aircraft can lift a lot of ordnance and deliver it with exceptional lethality, but serves best in a ground attack and support role, as its performance at high altitudes is poor.

Aircraft Statistics:

Maximum internal fuel: 170 gallons
Normal takeoff weight: 11,000
Stall, clean (pwr off): 104 mph (11,000 lbs)
Stall, landing (pwr off): 91 mph (11,000 lbs)
